Answer:

-3.

Step-by-step explanation:

In the table, the y value goes down by -4 and then -2, for a total of -6.

We did this over a period of two units (To go from -1 to 1, we add 2).

-6/2 = -3.

-3 is the average rate of change over the interval.

QUICK FAST HURRY ANSWER PLEASE 2 3/4 * 1 1/4 WILL BRAINLY IF ANSWERED CORRECTLY

Ierofanga [76]

1. 2 3/4 = 11/4(2 * 4 + 3)
2. 1 1/4 = 5/4(1 * 4 + 1)

11/4 * 5/4 = 55/16 OR 3 7/16 if simplified.

Answer:

The measure of ∠z = 137°

Step-by-step explanation:

Here, angle 1 = 43°

To find : ∠z

Straight line Angle: The angle which measures exactly 180° and is extended by a point on a straight line is called straight angle.

According to the given figure:

∠1 + ∠z = 180 ° (STRAIGHT LINE ANGLE)

or, ∠z = 180 ° - 43° = 137°

Hence, the measure of ∠z = 137°.

boyakko [2]

Answer:

5 meters.

Step-by-step explanation:

Given:

Mr. Dyer is leaning a ladder against the side of his house to repair the roof.

The top of the ladder reaches the roof, which is 3 meters high.

The base of the ladder is 4 meters away from the house, where Mr. Dyer's son is holding it steady.

Question asked:

How long is the ladder?

Solution:

<em>Here we found that a right angle triangle is formed in which base and height is given and we have to find the longest side of the triangle.</em>

Base = 4 meters

Height = 3 meters

Length of the ladder = ?

<u>By Pythagoras theorem: </u>

Square of longest side = Square of base + Square of height

$(Longest\ side)^{2} = 4^{2} +3^{2}$

$(Longest\ side)^{2} = 16+9$

$(Longest\ side)^{2} = 25$

Taking root both side :-

$\sqrt[2]{(Longest\ side)^{2} } =\sqrt[2]{25}$

$Longest\ side = \sqrt[2]{5\times5} \\ Longest\ side = 5$

Thus, length of ladder is 5 meters.
